ABSTRACT Lychee fruit has been studied owing to the presence of several bioactive compounds that can contribute to weight loss in obese individuals. However, the anti-obese potential of the fruit has not been explored yet. The aim of this study was to investigate the effect of different parts of lychee in reducing the adipose tissue mass of cafeteria diet-fed rats. Phenolic compounds and scavenging capacities were quantified. The food intake, apparent digestibility, weight of the body and liver, body mass, Lee Index, and the mass of epididymal and visceral adipose tissues were evaluated. The results were estimated by Tukey’s Test at 5% probability. A higher amount of phenolic compounds and scavenging capacity were observed in the peel of lychee as compared to the other parts of the fruit. The hypercaloric diet with lychee flour resulted in a higher apparent digestibility. There was no difference between groups control (C), hypercaloric (H), hypercaloric with lychee flour - 50.00% peel and 50.00% seeds (H2F), and hypercaloric with lychee flour - 33.33% peel, 33.33% pulp and 33.34% seeds (H3F) with respect to body and liver weight, corporal mass, and Lee Index. The hypercaloric diet-fed group exhibited an increase in visceral and epididymal adipose tissue mass, whereas the group fed with hypercaloric diets and flour made from the peel and seed of lychee presented a lower visceral adipose tissue mass. In conclusion, the use of lychee flour was considered viable because it decreased visceral adipose tissue mass in rats.
Summary The objective of this study was to use the pulp of the Brazilian Savannah fruits araticum and cagaita to develop new products, and to evaluate their sensory acceptance by children from 7 to 9 years of age. The products developed were: three milk caramel formulations: DP (standard), DA (araticum pulp) and DB (araticum pulp and grated coconut); three cagaita refresher formulations: RP (cagaita pulp), RA (cagaita pulp and orange juice) and RB (cagaita pulp and carrot juice); and a cagaita jam formulation. It was found that the three formulations of milk caramels were equally accepted (p>0.05), whereas the RA refresher was more accepted (p<0.05) than the others (RP and RB). In addition, the cagaita jam received high sensory acceptance scores. All the products developed were well accepted since their acceptability indexes were greater than 70%. There was no influence (p>0.05) of gender on the sensory acceptability of the products evaluated. It was concluded that the products developed showed good acceptability from a sensory point of view, which suggests high market potential.
Resumo O objetivo deste estudo foi utilizar a polpa dos frutos do Cerrado brasileiro araticum e cagaita para desenvolver novos produtos e avaliar a aceitabilidade sensorial por crianças de 7 a 9 anos de idade. Os produtos desenvolvidos foram: três formulações de doce de leite: DP (padrão), DA (com polpa de araticum) e DB (com polpa de araticum e coco ralado); três formulações de refresco de cagaita: RP (polpa de cagaita), RA (polpa de cagaita e suco de laranja) e RB (polpa de cagaita e suco de cenoura); e uma formulação de geleia de cagaita. Verificou-se que as três formulações de doce de leite foram igualmente aceitas (p>0,05), enquanto o refresco RA foi mais aceito (p<0,05) que os demais (RP e RB). Além disso, a geleia de cagaita apresentou elevados escores de aceitação sensorial. Todos os produtos desenvolvidos foram bem aceitos, uma vez que seus índices de aceitabilidade foram maiores que 70%. Não houve influência (p>0,05) do gênero sobre a aceitabilidade sensorial dos produtos avaliados. Conclui-se que os produtos desenvolvidos apresentaram boa aceitabilidade do ponto de vista sensorial, o que sugere um elevado potencial de mercado.
